What does 1,580÷25=I know the answer, I need to show how I got it.
ziro4ka [17]
\begin{gathered} \sqrt[25]{1580} \\ 1\text{ and 15 cannot divide 25 therefore, we use the first three numbers to divide 25} \\ \frac{158}{25}\text{ = }6\text{ remainder 8} \\ \text{You have to carry that remainder which is 8 and combine it with the 0 in 1580.} \\ \frac{80}{25}\text{ = }3\text{ remainder 5} \\ The\text{ remainder 5 will also divide 25} \\ \frac{5}{25}=0.2 \\ The\text{ quotient values are 63 + 0.2 = 63.2} \end{gathered}

Solve -2= -(x-8), justifying each step with an algebraic property PLZ HELP
vredina [299]
-2 = -(x-8)
-2 = -x + 8   ( - * + = -  and - * - = + )

-2 - 8 = -x +8 - 8
-2 - 8 = -x 
-(2+8) = - x
-10 = -x     | * (-1)

Evaluate 3x - 4y + 11 for x = -2 and y = -1
katrin [286]

Answer:

9

Step-by-step explanation:

Plug in -2 for x, and -1 for y, and solve:

3x - 4y + 11

3(-2) - 4(-1) + 11

Remember to follow PEMDAS. First, multiply. Remember, that when you multiply:

2 positive signs will result in a positive answer.

1 positive & 1 negative will result in a negative answer.

2 negative will result in a positive answer.

3 * -2 = -6

-4 * -1 = 4

-6 + 4 + 11 = 9

9 is your answer.
